C#.NET — Predict output with general exception handling and out-of-range index. Input provided: "6". What is printed?

Difficulty: Easy

Correct Answer: Exception occurred Remaining program

Explanation:


Introduction / Context:
This program converts input to an index and assigns val = 66 to a[index] in a 5-element array. It uses a single catch(Exception) block. We input "6" to trigger an out-of-range access.



Given Data / Assumptions:

  • Array: int[] a = new int[5]; valid indices 0..4.
  • Input: "6" → index = 6.
  • Assignment: a[6] = 66; causes IndexOutOfRangeException.
  • catch(Exception e) prints "Exception occurred " then execution continues to print "Remaining program ".


Concept / Approach:
Any exception thrown within the try block is caught by the general catch(Exception). After handling, the program continues unless rethrow or exit is used.



Step-by-Step Solution:

index = 6 → a[6] access throws IndexOutOfRangeException. catch(Exception) executes → prints "Exception occurred ". Next, the final Console.Write prints "Remaining program ". Combined output: "Exception occurred Remaining program".


Verification / Alternative check:
If index were 2, no exception would occur and output would be only "Remaining program ".



Why Other Options Are Wrong:

  • A/B: Incomplete; the program prints both messages.
  • D: Order is reversed; catch prints first.
  • E: Index 6 is invalid, so no assignment occurs.


Common Pitfalls:
Assuming execution halts after an exception when it is actually caught and handled.



Final Answer:
Exception occurred Remaining program
